Firefighters continue to make steady progress from the air and ground, as containment of the Rim Fire has grown to 70 percent. Total acreage burned stood at 235,841 Monday evening. Update: 9:30 p.m.

Firefighters continue to make steady progress from the air and ground, as containment of the Rim Fire has grown to 70 percent. Total acreage burned stood at 235,841 Monday evening.

Very active fire behavior was observed today on the south and east fire perimeters. Types of fire seen today included running ground fire, group tree torching, short crown runs, and spotting. In the north and west fire perimeter moderate rates of spread were observed both in advancing ground fire, and burnout operations.

Good progress was made with burnout operations in the north and southeast sections. Reliance on aviation resources has been critical in an effort to slow the fires progress to allow suppression resources to establish control lines in areas where accessibility and safety can be achieved.

The extremely dry fuels, high winds, and potential for long-range spotting remain a significant concern for the fire to advance beyond control lines.

Firefighters are gaining ground on the Rim Fire, as containment has reached 60 percent, although the fire continues to grow, but at a slower pace. The fire grew more than 8,300 acres overnight, and stood at 231,088 acres as of early today.

Burnout operations on the northern and southern portions of the fire continued with success through the night. Southwest transport winds returned smoke to the communities northeast of the fire, including Reno, Carson City, Markleeville, Minden, and the Lake Tahoe Basin, and returned clearer skies to the Yosemite Valley, El Portal, and the San Joaquin Valley.

USFS Fire UpdateLine construction combined with burning operations continued overnight where safe conditions and accessibility allowed on the east and southeast flanks of the fire. There has been good progress made on the spot fires occurring near Pilot Peak and along the southern perimeter.

Fire activity continues to be active in the south and southeast with moderate rates of spread and torching. Today winds will be coming from the south southwest with up to 20mph gusts. Fire activity has been slow and moderate in the north end of the fire.

Today’s fire weather is extreme. Very active fire and extensive spotting continues to hamper suppression efforts and pose risks to firefighters. Air resources continue to be utilized in assistance with spot fires, slowing fire advancement, and control lines in advance of the fire spread.

Update: 12 a.m. - Progress Continues, Smoke Reaches Yosemite Valley

Smoke from the Rim Fire has reached Yosemite Valley, as firefighters continue to make progress. The fire has grown to 224,777 acres, or 351 square miles. Containment is at 45 percent as of late Sunday.

Fire officials say good progress was made on containing a 61-acre spot fire southeast of Pilot Peak Lookout Sunday. Burning operations and structure protection continue on the southeast and northern edges of the fire.

Smoke from the fire has reached the popular tourist areas of the Yosemite Valley. To date, 11 residences have been destroyed, along with 97 outbuildings and three commercial buildings. Total cost is $66 million. See the Rim Fire Fact Sheet.

The fire became very active Sunday afternoon after the inversion broke. Running surface fire, torching, crowning, and spotting were observed on the fires south and east perimeters. Moderate rates of spread were observed both in advancing surface fire and backing fire on the northern and western fire perimeters.

Heavy fuels still continue to experience complete combustion with high probability of combustion.

Smoke in Yosemite Valley as seen from the Yosemite Falls webcam at 11 a.m. Sunday. The same view is show below at 1 p.m., as the smoke cleared.

Burnout operations have been temporarily suspended south of Hetch Hetchy Reservoir inside Yosemite National Park while fire behavior analysts and long-term analysts assess possibilities for opportunities for direct line construction south of Harden Lake.

Crews were successful in establishing more of a buffer between designated containment lines and the head of the main fire. In multiple areas more handline is being constructed for containment where deemed safe. Bulldozers worked to enhance the stability of contingency lines amid the fire’s edge and communities of Tuolomne City, Twain Harte and Long Barn.

Firefighters remain actively engaged in mop-up operations along the west flank of the fire in the Pine Mountain LAke and Buck Meadows areas. Significant progress has been made on burnout operations between Hells Mountain and Clavey Lake. Additionally, provided favorable conditions remain, more crews are expected to carry on with burning and structure defense operations throughout the night with the exception of the above mentioned areas temporarily suspended.

Fire Behavior

Very active fire behavior observed today on the south and east fire perimeters. Running surface fire, group tree torching, short crown runs and spotting. Moderate rates of spread were observed both in advancing fire and backing fire on the northern and western fire perimeters. Heavy fuels still continue to experience complete combustion with high probability of ignition.

Significant Events

Good progress was made with burnout operations on the northwestern and southwestern edges of the fire. Mandatory evacuations continue south of HWY 120 towards Yosemite National Park north of the Old Yosemite Road. There is a closure of Tioga Road west of Yosemite Creek Picnic Area. A Stanislaus National Forest closure order is in effect for locations near and in advance of the fire. The evacuation advisory continues for areas east of Highway 108 from Ponderosa Hills north to Pinecrest. Several locations to the west side of Yosemite National Park have also had closures implemented as a result of the fire's spread. Access and difficult terrain remain concerns for crews and equipment.

Outlook

Planned Actions

Wildland Fire Modules will be assigned north of Cherry and Eleanor Lakes to monitor the fires advancement and contain spread in the rocky terrain with fingers of sparse fuels. Direct and indirect line construction with burnout as necessary south of Harden Lake in Yosemite National Park. Continued burnout operations planned in Yosemite National Park along Tioga Road as favorable conditions allow. Patrol and mopup in all areas except the southeastern edge.

Growth Potential

Extreme

Terrain Difficulty

Extreme

Remarks

Very active fire and extensive spotting continue to hamper suppression efforts and pose risks to firefighters. Type 1 helicopters are providing point protection and cooling areas where direct line construction can be achieved safely. Approximately 4,500 structures remain threatened in advance of the fire on both the east and west sides. Fire is expected to continue its eastward spread father into the west side of Yosemite National Park east of Aspen Valley.

Due to inaccessible steep terrain and extreme fire behavior suppression efforts on active portions of the fire are being significantly challenged. Heavy reliance on aviation resources has been critical in an effort to slow the fire's progress to allow suppression resources to establish indirect control lines in areas where accessibility and safety can be achieved. The availability of heavy aircraft is pertinent to the success of suppression efforts.

Continued warmer and drier weather is forecasted for the next several days, which will elevate control concerns and slow burnout progress. Remotely piloted aircraft is providing realtime visual and infrared intelligence on the fire. Continued unified command with CAL-FIRE.
